RECEPTACLE-CLAMPING DEVICE.

Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed. September 24-, 1910. Serial lie 583,649.

To aZZ whom it may concern:

Be it known that I, VVINFIELD B. \VIL- LIAMS, citizen of the UnitedStates, residing at Vaxahachie, in the county of Ellis and State ofTexas, have invented certain new and useful Improvements in Receptacle-Clamping Devices, of which the following is a specification.

This invention relates to clamping devices for receptacles.

The object of the invention is to provide a plurality o1 clampingdevices whereby one receptacle may be clamped in another and the deviceis so constructed that they may be expeditiously operated to eitherclamp the receptacle or release it.

Finally the object of the invention is to provide means of the characterdescribed that will be strong, durable, efiicient, and easy ofoperation, simple and comparatively inexpensive to construct, and alsoin which the several parts will not be likely to get out of workingorder.

With the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in this specification and illustrated in theaccompanying drawings, wherein:

Figure l. is a view showing a tub in vertical section with a receptaclein elevation placed in the tub and a pair of the clamping devicesattached to the tub, one of said devices being in clamping position andthe other out of clamping position, Fig. 2. is a vertical sectional Viewof one of the clamping devices, Fig. 3. is a plan view of one of theclamping devices, and Fig. 4. is a vertical sectional view on the lineSS of Fig. 2.

It is to be understood that this invention may be employed where it isdesired to secure one receptacle in another of a greater diameter and inexplaining a form of the invention and one of its uses I haveillustrated in the drawings a packing tub 1 and a metal container 2 suchas are used in transporting ice cream and ices.

As the clamping devices are substantially identical in construction, adescription of one will suffice for both.

A base plate 3 is secured to the inside of the tub 1 a short distancebelow the top of the same and from this plate a shank 4 extends atsubstantially right angles thereto. The shank is substantially square incross section and is provided with a plurality of transverse holes 5. Onthis shank a locking lever 6 and a clamping arm 7 are mounted.

The locking lever has a general U-shape and is provided with a handleportion 8, the latter being curved so as to direct it away from the tubl and give suflicient room therebetween to enable the operator to freelygrasp the said handle portion. Each free end of the lever is providedwith an inclined boss 9. The faces of the bosses while substantiallyparallel incline upward toward the container 2 when the lever is in itslocking position as shown in Fig. 2, while their inclination is reversedwhen the lever is swung to release the container as shown at the righthand side of Fig. 1. From this it is obvious that the faces of thebosses incline at an angle other than aright angle from the shank 4:. Asshown in Fig. 2 the bosses are off-set one from the other thus savingmaterial in constructing the lever.

Near its upper end the arm 7 is provided with an elongated opening 10through which the shank 4 is passed. A cotter pin 11 is passed throughthe arm 7 and one of the holes 5. The elongated opening 10 permits thearm to be swung on the pin 11 which forms a pivot. The lever 6 at itsfree end is provided with circular openings 12 through which the shank 4passes and whereby the lever may be freely rota-ted on the shank, theedges of the latter being rounded as is shown in the drawings.

The arm 7 is positioned between the inclined faces of the bosses andthere is a slight play to permit the lever to be freely turned. At itslower end the arm is curved outward and supports a curved clampingmember 13 secured thereon by a screw 14: as shown in Fig. 2 or madeintegral therewith if desired. This clamping member may be made of rigidmaterial or of resilient material and frictionally engages the container2 to hold the same in place.

t is obvious that the clamping devices are placed on opposite sides ofthe packer tub as shown in Fig. 1. By swinging the levers 6 in onedirection the locking arms 7 are thrown away from the container 2, thelevers acting as cams and the direction of inclination being reversed asthe levers are swung. hen the levers are swung in the opposite directionthe clamping arms are swung on their pivots so that the clamping devices13 frictionally engage the container 2 on opposite sides. It is apparentthat the container is released by merely swinging the levers. Where themembers 13 are made of resilient material they Will conform to thecontours of containers of different shapes. By reason of the holes 5 theclamping arms may be set to clamp containers of diflerent diameters.

What I claim is:

1. In a receptacle clamping device, a base plate, a shank extending fromthe base plate, a clamping arm pivoted on the shank, and a locking levermounted on the shank and having inclined bosses between which theclamping arm extends.

2. In a receptacle clamping device, abase plate, a shank extending fromthe base plate and exhibiting a square shape in cross section, anon-rotating clamping arm pivoted on the shank, and a locking leverrotatably mounted on the shank and having inclined bosses between whichthe clamping arm extends.

3. The combination with a receptable and a second receptacle disposedtherein, of a pair of clamping devices each comprising a base plate,secured to the inside of the first receptacle, a support extending fromthe base plate, a clamping arm pivoted on the support and engaging atits lower end the sec- 0nd receptacle, and a rotating lever mounted onthe support and engaging the clamping arm, the clamping arms engagingthe second receptacle in opposed relation.

4L. The combination with a receptacle and a second receptacle disposedtherein, of a pair of clamping devices each comprising a base platesecured to the inside of the first receptacle near its upper end, asupport carried by the base plate, a non-rotating clamping arm pivotedon the support and adapted to engage the upper portion of the secondreceptacle, and a rotatable lever mounted on the support and having aninclined surface on each side of the clamping arm.

The combination with a receptacle and a second receptacle disposedtherein, of a pair of clamping devices each comprising a base platesecured to the inside of the first receptacle near its upper end, anon-rotating clamping arm pivotally supported by the base plate, aclamping member on the lower end of the arm, and a locking leverrotatably supported by the base plate provided with inclined bossesstraddling the upper end of the clamping arm, the clamping membersadapted to engage the second receptacle in opposed relation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
